Throwback Thursday: What is the Sun made of?

It’s the greatest source of energy in the Universe, and yet we had no idea until less than 100 years ago.

“The sun is a miasma
Of incandescent plasma
The sun’s not simply made out of gas
No, no, no
The sun is a quagmire
It’s not made of fire
Forget what you’ve been told in the past” -They Might Be Giants
